Bump github.com/BurntSushi/toml from 1.2.1 to 1.3.1

[dependabot]

Bumps github.com/BurntSushi/toml from 1.2.1 to 1.3.1.

Release notes

Sourced from github.com/BurntSushi/toml's releases.

v1.3.1

This fixes two small bugs:

• The BURNTSUSHI_TOML_110 environment variable would be checked on package import, rather than Decode().

  This meant that setting os.Setenv("BURNTSUSHI_TOML_110", "") had no effect, as it happens after the import.

• Fix order of Meta.Keys() for inline tables (this has been an issue since support for inline tables was added).

v1.3.0

New features:

• Support upcoming TOML 1.1

  While it looks like TOML 1.1 is mostly stable and I don't expect any further major changes, there are NO compatibility guarantees as it is NOT yet released and anything can still change.

  To use it, set the BURNTSUSHI_TOML_110 environment variable to any value, which can be done either with os.SetEnv() or by the user running a program.

  A full list is changes is available in the TOML ChangeLog; the two most notable ones are that newlines and trailing commas are now allowed in inline tables, and Unicode in bare keys can now be used – this is now a valid document:

  lëttërs = {
    ä = "a with diaeresis",
    è = "e with accent grave",
  }
  

• Allow MarshalTOML and MarshalText to be used on the document type itself, instead of only fields (#383).

Bufixes:

• \ escapes at the end of line weren't processed correctly in multiline strings (#372).

• Read over UTF-8 BOM (#381).

• omitempty struct tag did not work for pointer values (#371).

• Fix encoding anonymous structs on 32bit systems (#374).
